This paper proposes a Markov Decision Process (MDP) approach to compute theoptimal on-line speed scaling policy to minimize the energy consumption of a processor executinga finite or infinite set of jobs with real-time constraints. The policy is computed off-line but usedon-line. We provide several qualitative properties of the optimal policy: monotonicity with respectto the jobs parameters, comparison with on-line deterministic algorithms. Numerical experimentsshow that our proposition performs well when compared with off-line optimal solutions and outperformson-line solutions oblivious to statistical information on the jobs. Several extensions arealso explained when speed changes as well as context switch costs are taken into account. Non...
